AI Technical Summary
The high moisture content in the hot air generated by the air source heat pump results in a high saturated vapor pressure of the humid air, which reduces the driving force for moisture evaporation, prolongs the material drying time, and causes more heat to be used to evaporate moisture rather than heat the material.
A U-shaped hollow air inlet box is installed between the heat pump outlet and the dryer inlet. The box is filled with silica gel desiccant and a filter element. The hot air is evenly distributed to the silica gel desiccant layer through a ring-shaped air intake structure for dehumidification and filtration, reducing the humidity of the hot air. The air is then sent into the dryer by a fan.
Effective control of hot air humidity ensures rapid temperature rise, shortens drying time, improves drying efficiency, reduces energy consumption, and avoids material quality problems through uniform moisture evaporation.
